T azz whom m mom Be it known} thatI, DAviD LEETE KANE, a citizen of theUnited States, residing at Oakley, Cincinnati, in the county of Hamiltonand State of Ohio, have invented new and useful Improvements Rules, ofwhich the following is a specification,

This invention relates to rules and level devices such. as areused bybricklayers, ma; sons, and like artisans, the primary object beingtoprovide a deviceof this character which is sectional in constructionwhereby the sections may be separated and stored conveniently intool-box, or the like for the purpose of transportation.

A further obj ect ofthe invention is to provide a sectional rule whosesections are-constructed so that they may be joined securely and in truealinement witheach other.

A still further object is to provide a rule of this naturevhose-sections are each composed of a body of soft wood or the like, andfacing strips therefor which are constructed of hard wood, or otherdurable material.

The invention consists in thefeatures of construction, combination, andarrangement of parts, hereinafter fully described and claimed, referencebeing had to the accompanying drawings, in which:

Figure 1 1s a fragmentary side elevation of the device; Fig. 2 is atransverse sectional view on line 2-2 of Fig. 1; Fig. 3 is alongitudinal sectional view on line 33 of Fig. 2; Fig. 4t is a similarsectional view on line 4:"4: of Fig. 2; Fig. 5 is a vertical sectionalview on line 55 of Fig. 2; Fig. 6 is a perspective view of the joint endof one rule section; and, Fig. 7 is a similar view of the said sectionend looking at the same from the opposite side.

Referring to the drawings, is will be seen that the body of the rule isdivided into three sections, which include the terminal sections 1 and 2and the intermediate section 8, each of which includes a body portion 4which is constructed of some soft and inexpensive wood, or the like.Facing strips 5 of hard wood are secured in suitable manner to the upperand lower edges of the body of the intermediate section and terminate inspaced relation to the ends thereof with the beveled faces 6.

Each terminal section is provided in its inner end, and the intermediatesection in each of its ends, with a longitudinally taper- ;dove-tailedrecess 7 equal in depth to one-half the thickness of the body and openmgthrough its end face and one side face thereof. 7 A longitudinallytapering and section end, the tongue of the latter section being adaptedto fit within the socket of the first section. The endface 9 of eachtongue is inclined correspondingly with the inner endwall 10 of thereceiving recess of the coacting. section, whereby the joint will be .5;

rendered more secure when the sections are united. In order tostrengthen the joint further, the end faces of the body of each sectionabove and below its recess are inclined as at 11, and the adjacent facesabove and below the tongue are correspondingly inclined as at 12, inparallel relationto the faces 11, whereby a vertical, longitudinallyextending shoulder 13 is formed between the same to resist lateral,relative movement of the joined section ends. Transverse openings 14 areprovided in the tongue and in the inner wall of the recess of eachsection end, which are adapted to aline with similar openings in theinterlocking parts of the coacting section end for the reception of theconnecting bolt members 15, which in this instance are shown to be ofthe type com monly known as saw handle screws, in order that there willbe no outwardly projecting ends, the heads thereof being countersunk inthe outer side faces of the body portions of the respective sections.

At each joint between the sections, detachable facing strip sections 16are fitted against the upper and lower edges of the meeting ends instaggered relation to the joint and have their ends beveledcorrespondingly to the ends 6 of the permanently connected facing stripsections for even engagement, therewith. These detachable sectionsextend to the outer ends of the terminal sections of the rule body, andare adapted to be connected at their opposite ends to the respectivesection ends of the rule by means of the vertical securing bolts 17,which are mounted within the openings 18 therein.

As shown in the drawings, the terminal sections of the rule are providedpreferably with spirit tubes 19 which are arranged at i ing spirit tube20 is provided medially witha in the intermediate section for use inlevelmay be joined together in such a manner as to provide a body whosestraight edges are mitrue almement and unlnterrupted. When i thesections aredisconnected, they may be r and hardwood facing stripstherefor, and 7 1 right angles to the longitudinal axis of the rule andare thus adapted for use in planing vertical surfaces. A longitudinallyextend ing' horizontal surfaces. I V a a From the foregoing descrlptlon,taken in connection with the accompanyingdrawings,"it should be apparentthat I have provided a combined rule and level device which is adaptedto be manufactured cheaply, and is composed ofdetachable sections whichstoredrconveniently in a minimum amount of space, whereby thetransportation of the device in the ordinary tool-klt'from place toplace, as is often found desirable in practice,-

will be facilitated.

-- The main features of the construction are theprovision of separablesections,,each'of which includes. a body that maybe constructed-of softwood or the like material,

the specific form of interlocking joint between the sections. Itisto beunderstood, however, that minor changes in the details of construction,suchas fall within the scope Copies ofrthis patent may be obtained forof the appended claim,may be resorted to V inpractice whenevernecessary. a

What is claimed is: a 1

A rule of theclass described comprising an elongated body includingseparable sections, one end of each section being provided with alongitudinally taperingdovetailed recess opening through one of its sidefaces, a longitudinally tapering dove-tailed projection formed upon thesaid end of each section in prolongation of the inner wall of the recessforreception within the recess of V the companion section when thesections are united, and means for securing the tongue of one sectionend detachably within the recess of the other section end, the'joint endof each section being provided above and below its recess andtonguerespectively with parallel, longitudinally inclined faces-form,ing shoulders therebetween adapted 'to interlock with thevcorresponding shoulders of the coacting joint end of the adjacentsection; 1
